Morphology
The term is compositional: 'troy' names the troy weight system (used for precious metals) and 'pound' names a unit of weight, so together they denote the pound as defined within the troy system. While the exact ounce conversion (12 troy ounces) is a technical detail not automatically computed by learners, the basic meaning 'a pound in the troy system / a weight unit for metals' is directly derivable from the constituents and is cross-linguistically transparent.
Etymology
The name troy pound may come from the old French town of Troyes, where long ago merchants at big markets used a special set of weights for gold and silver. That's why troy pound became the 'unit of weight' we still use for 'precious metals'.
